Overhauling a CHP unit is an important service intervention that restores the performance and reliability of the machine. During this overhaul, all important components of the unit are checked (and replaced if necessary) to ensure the unit’s optimum operation. The repair includes servicing the engine, generator and replacing worn parts, and other service work. This will ensure reliable operation of the CHP unit, increase the efficiency of its operation and prevent unexpected CHP unit downtimes.
CHP units can interact with the master distribution system in several basic operating models. In parallel operation, the unit is operated in parallel with the main distribution network, allowing the generation of power and heat for the local consumption while the surplus electric power can be sold to the grid. In island operation, the unit operates independently of the external grid, which is useful in the event of a power outage or in remote areas. Emergency operation ensures an uninterrupted supply of power and heat in the event of an emergency. These modes of operation bring flexibility and reliability to the power systems.

Online monitoring of CHP units enables real-time monitoring of the operation and technical status of CHP units thanks to the Internet connection and a secure interface. The CHP unit can be started or shut down remotely and other settings are available. This enables responding to the non-standard machine conditions quickly and often even preventing them. This also saves money, as the available data significantly reduces the downtime of the CHP unit.
CHP units are significantly more efficient than the coal-fired power plants. They burn coal to produce electric power with an efficiency of around 35-40% and high CO2 emissions. In contrast, CHP units produce the power and heat from a single source achieving efficiencies of over 90% and minimizing a heat loss. This reduces CO2 emissions per the unit of power and heat produced which is crucial to reducing the environmental impact and increasing the energy sustainability.
By generating the power and heat from a single fuel, CHP units increase their energy efficiency and reduce the need for fossil fuels. This significantly reduces the greenhouse gas emissions compared to traditional energy sources, including CO2, which is a major cause of global warming. CHP units reduce the energy waste and dependence on traditional energy sources, contributing to sustainability and environmental protection.
The exhaust heat exchanger is an optional part of the CHP unit that serves to increase the overall energy efficiency. Its main function is to utilize the warm waste exhaust gases generated in the electric power generation process and convert them into a hot water or air. In this way, the heat loss is minimized and the overall energy efficiency of the system is increased. The exhaust heat exchangers thus contribute to the sustainability and efficiency of the gen-set.
A CHP unit is an energy device that simultaneously produces electric power and hot water from a single source (fuels may vary: natural gas, different types of biogas, etc.). This process uses the waste heat generated by the electric power generation, thereby increasing efficiency and reducing energy costs. CHP units find applications in many areas where they help to reduce the greenhouse gas emissions. In addition, the flexibility of their operation makes the CHP units crucial for the modern energy sector as they complement well with RSE.
